APPARATUS FOR TRUCKS OF RAlLWAY-CARRIAGES.

Specification of Letters Patent.

Patented Jan. 22, 1907.

Application filed October 19,1906. Serial No. 339,709.

To all whom, it may concern.-

Be it known that I, WILHELM LAUTEN- soHLAeER, of Pinerolo, near Turin,Italy,

have invented certain new and useful Improvements in Pull-Back Apparatusfor Trucks of Railway-Carriages or the Wheels of Automobiles, of whichthe following, taken in connection with the accompanying drawings, is afull, clear, and exact description.

My invention chiefly relates to shifting and swiveling trucks forrailway-carriages and the object is to provide a simple and efficientmeans for bringing back the truck or bogie to its central position afterit has been displaced.

The invention consists in fitting the truck or bogie with arms rotatingabout pins on the truck or bogie and connected by a spring so as to drawtheir ends together, checks for the other ends of the arms beingprovided at the truck or bogie and the car-body in such a manner thatwhen the truck or bogie is in its central position every lever is incontact with one check on the car-body and the neighboring check on thetruck or bogie frame.

I desire it to be understood that the invention is not to be limited torailway or tramway carriages, but that it may. also be applied to theswiveling wheels of street-carri ages, such as automobiles or the like.

In the drawings accompanying this speciiication and forming a partthereof, Figure 1 is a front end view of a shifting truck fitted withthe invention. Fig. 2 is a plan view of Fig. 3 is a front end view of aswiveling truck or bogie. Fig. 4 is a side elevation of part of thebogie shown in Fig. 3, and Fig. 5 is a plan view of Fig. 3.

Referring to the drawings, in Figs. 1 and 2, a is the car-body. bis theframe of the shifting truck. car-body on the truck. At a convenient partof the truclofrarne, preferably on its frontal girder, two double-armedlevers e and fare arranged to rotate about pins 9 and h.

when they are free to rotate.

A spring i connects two arms of the levers. This spring is fastened withsome tension, so as to draw the ends of the arms together On the frameI) checks is and Z are arranged for each of the free arms of the leversa and Similar checks m and n are arranged on the car-body c and d arearms for carrying the a in such a manner that in the central position ofthe truck the levers e and f are by the tension of the spring i pressedagainst both checks is and m and Z and n.

Figs. 3, 4, and 5 show the arrangement of the invention on a swivelingbogie. a is the car-body b, the bogie-frame. c is the center pin. e andf are the two-armed levers. i is the pull-pack spring, and 7c, Z, m, andn are the checks on the truck-frame b or the car-body a. respectively.

When the carriage runs through a curve, the truck or bogie is displacedfrom its central positionfor instance, to the right in Fig. 3. The checkn is then displaced to the left with relation to the truck or bogie andlifts the leverf from its check Z, as shown in dotted lines in Fig. 3,at the same time straining the spring 'Z. The lever e cannot leave itsposition, as it is held by the pin g and the check 7c. So altheugh itleaves the check m it is not influenced by the swiveling or shifting ofthe truck or bogie, but only pressed the tighter against the check lathe more the spring i is strained. When the carriage has left the curve,the spring 11 pulls the lever f back to its original position until itis in positive contact with both the checks n and Z.

I do not wish to be limited to the precise or exact form of constructionshown, as said construction may be changed in various ways withoutdeparting from my invention.

What I claim as new, and desire to secure by Letters Patent, 1s

1. The combination with a truck or bogie for railway-carriages and thelike of arms arranged to rotate on the frame of said truck or bogie,checks on the frame of said truck or bogie within the throw of saidarms, and means for keeping said arms in positive contact with saidchecks.

2. The combination with a truck or bogie for railway-carriages and thelike of arms arranged to rotate on the frame of said truck or bogie,checks on the frame of said truck or bogie within the throw of saidarms, checks on the car-body and means for keeping said arms in positivecontact with both the checks on the truck or bogie frame and thecar-body.

3. The combination with a truck or bogie for railway-carriages andthelike of arms arranged to rotate on the frame of said truck or Inwitness whereof I have hereunto signed bogie, checks on the frame ofsaid truck or my name, in the presence of two subscribing bogie withinthe throw of said arms, checks witnesses, this 8th dayof October, 1906.

on the car-body and a coiled spring for keep- VILHELM LAUTENSCHLAGER.

ing said arms in positive contact with both Witnesses: the checks on thetruck or bogie frame and GOTTARDO C. PINNI,
